Title: Improvements to tractors comprising traction couplings such as drag-hooks or draw-bars
IPC: B60D1/46
Filed: 1964-11-12
Abstract: 1,077,755. Tractors. MASKIN-PATENT A.S. Nov. 12, 1964 [Nov. 13, 1963], No. 46149/64. Heading A1P. A tractor comprising a traction coupling 12 such as a drag-hook, Figs. 1 and 2 (only Fig. 2 shown), or a draw bar, Fig. 3 (not shown), comprises a swinging- frame 5 pivoted to a second frame 3 fixed to the under side of the tractor (1), the traction coupling 12 being detachably attached to the swinging frame 5 which may be swung in a vertical plane by the tractor hydraulic lifting gear (6) so that the coupling is clamped between the swinging frame 5 and the tractor (1), as the swinging frame 5 locks itself to the second frame 3. The swinging frame- 5 is raised by chains 7 connected to lifting gear (6) until it is inside the second frame 3 where matched portions on the frame 5 lockingly engage gravity- or spring-loaded pawls 18 on the frame 3, the pawls being disengageable by the driver by means of a lever 19. The free end of coupling 12 rests on a crosspiece 11 of the frame 5, a raised platform on the coupling 12 engaging a notch 15 in the cross-piece 11, and the other end of the coupling 12 is supported on the under side of the cross-piece 10 of the frame 5, the coupling 12 having a slot 14 engaging a bolt 13 on the cross-piece 10. The coupling 12 may alternatively be located by means of a bolt (not shown) engaging a hole 20 in the coupling 12 and a hole 16 in the cross-piece 11. The bolt may be omitted. The eye of a trailer coupling is retained on the drag-hook in the raised position by a plate 20. In another embodiment, Fig. 3 (not shown), the coupling comprises a draw-bar (12) prevented from jumping by a bolt passing through a hole (22) in the drawbar (12) and retained by a split pin (23). The draw-bar may have an extension having one ormore extra slots.

Title: Wide deviation magnetic recording techniques
IPC: G11B20/06
Filed: 1970-09-30
Abstract: 1325734 Television WESTINGHOUSE ELECTRIC CORP 30 Sept 1970 [6 Oct 1969] 46423/70 Heading H4F In a system for recording a television signal s, v, b, having an amplitude-frequency characteristic B with a cut off point F 0  (5 MHz) on a medium with a predetermined bandwidth D (1 to 9 MHz) such as a magnetic tape, disc or drum, after clamping a selected (e.g. blanking) portion to a reference (e.g. zero) potential and preemphasis, the signal is frequency modulated on a carrier having a frequency at or near to F 0  so that the blanking portion b provides the carrier frequency, the video portion v provides frequencies extending from the carrier frequency to a point t w  (8À5 MHz) near the upper limit of D, and the synchronizing portion s provides frequencies in a range extending below the carrier frequency to a point F s  (3 MHz) within the frequency spectrum of the television signal. In this manner all of the bandwidth D above F 0  may be used for picture information, but cross modulation between the modulated and unmodulated signals is limited to the synchronizing portion, since the modulated video is confined to frequencies greater than F o . Any consequent distortion of the synchronizing signals may be corrected, for example, by including a non- linear amplifier in the pre-emphasis circuit used in recording which amplifies negative signals more than positive signals so that a horizontal sync pulse tip might provide a modulated signal at F e  (1À5 MHz) rather than F s . During replay the exaggerated sync. pulses are shaped by clipping.

Title: Internal combustion engine ignition systems
IPC: F02P3/045
Filed: 1963-12-05
Abstract: 994,861. Ignition systems. GENERAL MOTORS CORPORATION. Dec. 5, 1963 [Dec. 6, 1962], No. 48070/63. Heading F1B. In an internal-combustion engine ignition system the supply of current to the primary winding 28 of an ignition coil is controlled by a three terminal semi-conductor switch device 55, 70 which is adapted to be turned on and off by a control device 42 driven in synchronism with the engine and apparatus is included in the system for delaying the turning on of the switch device in accordance with engine speed and the period for which the switch device was turned on during a preceding cycle. The voltage induced in the pick up coil 50 builds up at a slow rate at low engine speeds and at a fast rate at high engine speeds. Accordingly a given charge on capacitor 90 will cause more time delay at low engine speed than at high engine speeds. At low engine speeds the "on" time of transistor 55 tends to be long but this increases the charge on the capacitor 90 supplied from the secondary winding 64 of the coupling transformer and therefore causes the "on" time to be shorter. At high speeds the "on" time of the transistor 55 tends to be short and this causes less charge to be supplied from the secondary winding 64 so that less delay and turn on of the transistor 55 results. Proper choice of circuit components will cause the "on" time of the transistor 55 at low speeds to be only slightly longer than at high speeds. A feedback coil not shown may be provided which is connected between one side of the primary winding 58 and the conductor 32. The term "three terminal semiconductor switch means" is intended to cover transistors and any other three terminal semiconductors such as controlled rectifiers which are capable of being used in place of transistors.

[Also in Division B1] Synthesis gas containing mainly H 2  and CO, with some CH 4  and C0 2 , is made by a two-stage catalytic cracking with steam of a hydrocarbon feedstock. The first stage, which produces a CH 4 -rich gas, is carried out in an unheated reactor at 350‹ to 550‹ C., and the second at 400‹ to 900‹ C. in an externally heated tubular reactor. Both stages employ Ni and/or Co catalysts. The internal surface area of the Ni or Co in the first catalyst is more than 20 sq.m./gram, preferably 30 to 300 sq.m/ gram, and the carrier is a precipitated oxide and/or silicate of Mg, Ca, Ba, Zn, Al and/or Ti.

[Class 64 (ii)] [Also in Group IV] In multi-layer heat insulation comprising spaced non-metallic foils, for instance of plastic artificial compounds such as cellulose esters, the foils are used of thickness thinner than that which corresponds to the minimum thickness at which the basis compound of the material is impermeable to heat radiation by embedding therein a filling agent, preferably finely divided, which decreases the permeability of the material to heat radiation.

Materials exemplified comprise lampblack, kaolin, heavy spar, gypsum, zinc white, platinum black, and colouring matters whether soluble or not in acetone; transparent materials may also be used. The average foil spacing is preferably 2À5 to 6 mm. The proportion by weight of embedding material to solid cellulose ranges from 2 to 20 per cent. In the preparation of embedding materials comprising colouring matters, a softening agent, such as tricresyl phosphate, is preferably added to the ball mill. The combustibility of the foils may be lessened by using compounds such as boric acid, sodium biborate, ammonium sulphate, antimonides, calcium sulphate, cerium oxalate, aluminium fluoride and phosphate, calcium and magnesium tartrate, and magnesium nitrate.
